It’s no secret that one of the major driving advancements in the near future will come from autonomous driving. So far, BMW models are offering Level 2 autonomous functions. That implies the cars can maintain a safe distance from the car ahead, keep you in lane and make driving in boring situations a lot easier. But Level 2 still requires the driver’s full input and attention, and that’s the reason why true Level 3 self-driving features are yet to arrive.
